Thanks to Keeps for sponsoring this episode of HiLow.

For the slalom test, the tires made a huge difference, Nolan. For both cars compared to stock, the low car ran a 6.57, and the hi car ran a 6.52, which is a 7.6% improvement over stock. A half-second difference over a 400-foot course is huge. That's really big, yeah. Massive.

And I also want to point out that hi car is now officially faster than low car. We're at one and one now, we're tied. So for the radial test, both cars were consistently breaking loose at around 40 miles an hour. The low car got up to around 39 miles per hour before they broke loose. Hi car was around 41. Two miles an hour - not huge. Not bad. But also - not nothing.

Yeah, not nothing. Nolan and I were bouncing like my wife (bleep). Finally, the 60-to-zero deceleration tests. Regardless of all our driver error and difficulty, we were able to get a pretty consistent data set. But when this car was new, it stopped at 120 feet. Hi car was a little bit better than low car, but both cars are considerably better than stock. There's just so much more contact - I would think maybe the compound has a little bit more to do with that than the width.

As far as wheels go, I don't think Nolan or I are good enough drivers to notice the difference in wheel performance. Basically, buy something nice enough that's not gonna break. Stay safe. And then it just comes down to how hard you want to flex.

Personally, I like my wheels better. I'm sorry, I'm not going to say the Advans look bad because they don't - they look amazing. But I like the XXR's better. I think they're great value for the money. Nolan wouldn't buy the XXR's. He would buy something slightly cheaper than the Advan. You have to pick one of the two.

If I had to pick one of the two, I would get the Advans because I have a reputation to uphold and I can't be rolling around on multi-lug pattern wheels. So Nolan, does more expensive mean more better? Technically, yes. Sort of. Definitely. Sort of, yes. Definitely, 100%. In every test, they perform better than your tires.

I know, but it's not like the suspension tests where it's like immediately apparent. Ask me which ones I would buy. Which tires would you buy, James? I would buy the Federals. Okay. I want a car that I can break the rear end loose when I want to. I'm with you on the Federals just because, not for the reason that you want a looser car but because you have to be such a better driver to feel any difference.

Also, I just want to address some comments from the last videos saying that we were sponsored by KW or that we're gonna be sponsored by the best parts in every episode. Not true, we bought all of those. Part that you see in this entire series. We paid for. Thank you for watching HiLow.

WEBVTTKind: captionsLanguage: en- No way.- Shut up.- $1000 set of wheels and tires.- Versus $3600 set of wheels and tires.- Does more expensivereally mean more better?- Let's find out.- Go.We bought two identical Nissan 350Z's.- Almost identical, asidentical as we could find.- We've been modifying them to be fun,daily drivers that youcan take to the track.- One Z gets expensive partsand the other Z gets cheap parts.- Then we're gonna test themto see which components areactually worth spendingyour hard-earned money on.- For my wheels, I wentwith a set of Advan RG3's.They're very strong,they're very lightweight.They're $667 a wheel, whichis nothing to sneeze at.And for tires, I went with theseBridgestone Potenza RE71Rs.They are $265 a tire.I got them on sale.- And on the cheaper side,I went with XXR 527 wheels.They're 127 bucks each.And for tires, I wentwith Federal 595 RS-RR's.They're only 136 bucks a tire.What do you say we open up our wheelsand see what they look like?- Those are sick, dude.We went with an 18 by10 square setup on my Z.This is light, dude.- Let's see what mine look like.I will be honest.I like the way mine look more than yours.- You like them more?- Yeah, I likethe more spoke-y look.- So why do mine cost sixtimes as much as Nolan's?Well, alloy wheels can bemade using different methodsthat determine their weight and strength.My Advans are flow formed.The process gives the wheels more strengthwithout adding more material,so they come out stronger and lighter.Each of them weighs in at about 20 pounds.- So mine are low pressure cast wheels.And they weigh about 24 pounds each.- So Nolan's suspensionis gonna have to work a little bit harderto control its heavierwheel than mine will.- And my wheel has what'scalled a multi-lug pattern,so this wheel can fiton many different cars,not as cool as the single lug pattern.- No, it's sort of a tellingthat your wheels are cheap.- Yeah, no, I'm gonnatry to keep this as nice.I'm gonna try to keep these, I'm sorry.I'm gonna try to keepthese as nice as possible.- So this is the first testyou gotta do with the tire,see how good they bounce.- Oh yeah.Rubber compounds are serious business.- Unlike rubber chickens,which are technically a joke business.- Tire companies are super protectiveof what's in their secret sauce.Plus, the government's tirequality grading standardsaren't strictly enforced.And the way manufacturers rate them allis kind of unverifiable too.It's just weird.- Yeah, so while theFederal 595 RS-RR tiresgoing on Nolan's car havea 200 treadwear rating,that doesn't mean thatthey'll perform the sameas my 200 treadwear Potenza RE71R's.It's time to stop beingpolite and start getting real.Can cheap tires match theperformance of expensive tires?- I hope so.- I hope so, I hope so too.I would much rather spend $500 than 1200.- Ridiculous.- All right, you can spendall the money in the worldon wheels and tires,but if they don't fit right,then they're gonna be areally expensive paperweightthat sits in your room forever.Ask me how I know.Unlike most projects,the hard work for fittingwheels and tires on your carcomes before you even open your toolbox.Research is the name of thegame here, boys and girls.- There are a lot of numbers on a tire,but there are only threethat you need to knowto make sure they fit on your car.The width, the profileor the aspect ratio,and the diameter.The width is self-explanatory.It's the width of the tire.So these are 265s.Generally, the wider a tireis, the more grip it will have.But the more rollingresistance it will have too.So it might eat up some gas mileage.- The second number is ameasurement of the side wallbut it's not in millimeters.It's what's called an aspect ratio.45 means that the side wall is 45%of the measurement of the width.So the width is 245 millimeters.This 45 means that theside wall is 45% of 245.- The smaller your tire aspect ratio,the less tendency of the tire to shiftback and forth on the wheel,the less rollover it has,but it'll be a lot harsher of a ride.You're pretty much riding on rubber bands.- And then the last number, that 18,that's just the diameterof the hole in the tire,so you know what sizewheel to stuff in it.And those are the thingsthat are important to knowwhether or not you canfit them under your car.So that's tires.That's pretty easy.- With wheels, there's alot of things to considerand a lot of scary numbers involved.But don't sweat it.Zach and Nolan are gonna break it down.I attempted to break it down.The more you move the center of,the more you move the hub.- There's really five numbersyou need to know with wheels.You need to know your diameter,so you need to know if it matches the tireyou're putting it into.- The next measurement is the width.And wider wheels lets you run wider tires.But you can also run skinnier tires.And if we really wantedto go full stance boy,we could put super skinnytires on our wide wheelsand kill ourselves when we'redriving over twisty roads.- You need to know your bolt pattern,and you need to know your hub center boreto know whether or not it will slip overthe hub on your car.So that's all important, butthat's all pretty simple.- The last measurement onthe wheel is the offset,and this is scary, but it's not, it's not.- To understand offset,let's first find zero offset.Zero offset is the deadcenter line of the wheel.And then when we talkabout positive offset,that means that we're movingthe mounting face ofthe wheel, this thing,we're moving that positively outwards.So towards the face ofthe wheel is positive.That's it.And then that lets you know how far outyour wheel's gonna poke or howfar in it's gonna be suckedand ultimately how it's gonna lookbecause an 18 by 10 couldfit a million different waysgiven a million different offsets.But with the internet, with our forums,we know what people run,we know what looks good,and so, we've got some targets to hit.- You definitely want tolook up the torque specsfor your lug nuts.You don't want to bedriving down the streetand have your wheels come off.I've been in a car whereit happened, not mine.It was, one, terrifying,and two, very embarrassing.Yes.We don't have to roll the fenders.- We have to roll the fendersbecause our wheels are very wideand the offset is relatively aggressive,so we're taking the fender lining out.If you did your math a little bit wrongor if you're just goingfull send on your fitment,you can buy yourself a fewextra millimeters of wiggle roomby rolling your fenders.This usually consists ofbending the inner lipof your fender upwardwithout really changingthe exterior look or shape of the panel.You can do it with a purposebuilt fender roller like this,or you can go old schoolwith some hammers.Nobody does it like this anymore.This is some real artisan, artisan stuff.- (bleep) I just broke something.- And it alwayshelps to add some heatto try and keep the paint from cracking.- I think we got plenty of room.I think the fender pullingand rolling did the trick.I don't think we're gonna rub at all.- So Nolan's car is slammed.- Clout god.- And I am honestly a little jealousthat his car is so slammed.- Gotta get lower, dude.I really love it, dude.- Let's go see if this puppy rubs any.- More, more, more.- You think it's gonna rub?- No.Hooks it up.- Hooks up, fo' sho.- Road noise on the new tires.- We got a little bit of rubbing.Yeah, there's a definitedrone to the tire noise.- These feel good,like around that kind of corner earlier,you could kinda feel itpush a little in the front.- It's like on rails, man.God, James's car is gonna feel amazing.- Damn, we're not even sureif it's second anymore.- No, we're just stuck to the road.- You have so muchconfidence with these tires.All the confidence we tookaway with the $300 coilovers,you get back with these tires.- But their tires at afraction of the priceare definitely 80% as good, if not more.- Dude, it's great.No rubbing, nothing.- We might have just rideheight it a little bit,but that's just 'causewe want to look doper.- It feels very planted,very confidence inducing,which might be a bad thingfor guys like me and Zach.I'm really happy with it.It feels really, really, really good.- What a combination of smells.I guess what we learned today is thathot boy isn't a choice, it's a lifestyle.- That's a good bang for your buck, man.I would be happy with that for 1300 bucks.That's legit.- Zach, are you ready?- I am ready.- Last episode,we set up a slalom courseto test the handling of ournew coilovers with stock tires.This time, we ran the same courseto see how much of a differenceour new thick, grippy boys made.- So I think for us to reallysee the limit of these tires,we need to be on a trackand really running hot laps,heat cycling the tires.I think the Federals and the Bridgestonesare gonna feel very similarfor what we're doing.- When you look at both runs side by side,you can clearly see thatlow car's Federal RS-RR'smaintain traction noticeablybetter than the stock car's.In hi car, the resultswere even more apparent,especially around the last cone.You can see here the rear end of hi carkick out with the stock tires,but with the Bridgestone RE71R's,that booty stayed solidly planted.Next up, we ran what'scalled a lateral G test.Basically, you drivearound in a big circleas fast as you can untilthe tires lose grip.If you've ever been on a merry-go-round,this is kinda like that but way more fun.And if you think about it,there's way more horses in this one.I'm talking hrsprs.Did you break it, Lewis?I didn't see.In this episode, we're testing the tires,but both cars havedifferent suspension setupsthat affect how they drive.- The low car was jouncing,bouncing all over the place,looked super unplanted,looked uncomfortable.- The front end was just sort of.- And the hi car, I couldhave done that all day.It was very comfortable.It was eating up every imperfectionas we were going around,and it felt very neutral.We eventually just kinda pushed it out,but it was hardly even over-steer.And I'm super happy withthe way this thing feels.- And finally, we conducteda 60 to zero deceleration test.You might think that thiswould be testing the brakes,but the traction of thetires actually playsthe biggest role inyour stopping distance.Turns out 60 to zero decelerationtests are really hard.- I got like 55.- Did you find it harder to dothan you thought it would be?- Yeah, yeah, 'cause I would get up to 65and be like, okay, I canlet off and it'll slow down.And then you let offand it's like, still 65,and I was like.- But we think that we were able to getenough good runs out of each carto draw some pretty decent conclusions.So does more expensive.- Mean more better?- The results are in.- And they may shock you.- They probably won't.Thanks to Keeps for sponsoringthis episode of HiLow.Are you like me, smart, handsome,too strong for your own good,but absolutely terrifiedof losing your
